Primary fluorescent chlorophyll catabolite
WebHere, we report that a variety of heterotrophic protists accumulate the chlorophyll a catabolite 13(2),17(3)-cyclopheophorbide a enol (cPPB-aE) after their ingestion of algae. This chlorophyll derivative is nonfluorescent in solution, and its inability to generate singlet oxygen in vitro qualifies it as a detoxified catabolite of chlorophyll a. WebThey include iron-containing heme, magnesium-containing chlorophyll, nickel-containing coenzyme F430 and cobalt-containing cobamide (such as vitamin B12 coenzyme) as shown in this map.

WebThe red chlorophyll catabolite (RCC) is a proposed cryptic intermediate of chlorophyll (Chl) breakdown in higher plants. Its accumulation in higher plants is believed to be metabolically suppressed, as RCC is commonly suspected to efficiently sensitize for the formation of the cell poison singlet oxygen (1 O 2).We report here a study on luminescence of the methyl … WebThese linear tetrapyrroles are generated from their fluorescent chlorophyll catabolite (FCC) precursors by a nonenzymatic isomerization inside the vacuole of senescing cells. Here, we identified a group of distinct dioxobilin-type chlorophyll catabolites (DCCs) as the major breakdown products in wild-type Arabidopsis, representing more than 90% of the …

WebMg2+ is removed from chlorophyll a by a dechelatase to form pheophytin a. The phytol in pheophytin a is hydrolyzed to generate pheophorbide a, and the porphyrin ring is then cleaved to generate a series of fluorescent compounds (such as the red chlorophyll catabolite, RCC, and the primary fluorescent chlorophyll catabolite, pFCC). WebThe structure of GH5, the globular domain of the linker histone H5 fold is similar to the DNA-binding domain of the catabolite gene activator protein, ... They may be grouped into at least three subfamilies based on primary sequence. One subfamily comprises yeast Emp24p and mammalian p24A.
Websenescence-related chlorophyll breakdown in vivo [9]. In the next-step reactions, the resulting pheophorbide (pheide) a is converted into a primary fluorescent chlorophyll catabolite (pFCC), which requires two enzymes including pheide a oxygenase (PAO) and red chl catabolite reductase (RCCR) [10–13]. PAO is identical to
WebRed chlorophyll catabolite (RCC) reductase (RCCR) and pheophorbide (Pheide) a oxygenase (PaO) catalyse the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of Pheide a to a primary fluorescent catabolite (pFCC).
